Fuel Pressure Safety Switch
Friday, September 23, 2005 9:02 PM
I searched and didn't find anything about this.

I was going to get one as a reassurance for my dry kit but ran into some questions.


The quote from one sold by NX
"Safety switches from Nitrous Express.
These EFI fuel pressure safety switches from Nitrous Express are designed to cut off the fuel supply if the pressure gets too low. This prevents a lean condition, which could harm your engine. "

Would this not create instant lean if the fuel is cut off while spraying?

Does it and if so how does it work for a dry kit?

This is probably a simple answered question but if you do not ask you do not know

Its meant for a wet kit because on a wet kit you add fuel so if it seems Fuel Pressure drop it will cut the nitrous out as well . . . .

It's meant for dry kits as well. It screws on to the end of your fuel rail, and if fuel pressure drops below a pre-set "safe" level, it cuts the power to your nitrous solenoids. It doesn't cut the fuel flow at all--at least, the NOS one doesn't.

Meant to screw into the fuel rail does that mean it is not made for our rail and has to be custom right?

Can you hook me up with a link to where it is sold?

Correct-

To mount it on the fuel rail like I did, you have to cut the end off and weld a fitting on. I'm not sure if you could use a T-fitting type setup instead, somewhere in the fuel line itself. I can't picture the setup off the top of my head right now.

Is there anyway I could get some pics? I am really interested in trying this.

It is only meant for a wet then, how does it hook up it for it?

I would think since it is made for a wet you could tee off the fuel line and hook it up the same as you would for the wet..
